Looking for a lesson on pack animals.



What is the good and the bad, the preferred as a pack animal. For arguments sake let's discuss pure pack animal to pack in gear, not ride.

Horse, Mule, Ass, Burro, what do you prefer for an exclusive pack animal.

Which are sure footed under load, which can pack the biggest load, which have bad behavior making them not worth the hassle? Can one get by with less water than another?

Thank you.
